Patented Sept. 8, 1931 am LQB Winn frwrsmrne ini-vien Application filed`Tune 18,

This invention relates to a wire twisting device particularly adaptedfor use'intighten- 5 object to provide, in a manner as hereinafter! setforth, a wire twisting device by means of which a comparativelyinaccessible pair of wires may be quickly and conveniently twisted totighten the same.

lVith the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement'of parts ashereinafter more particularly described, and as illustrated in theaccompany- 15 ing drawings wherein is shown an embodiment of theinvention, but it is to be understood that the description and drawingsare to be taken as illustrative and that the invention is intended to belimited only by the C23 scope of the claims hereunto appended.

In the accompanying drawings in which like numerals are employed todesignate like parts throughout the several views p Figure 1"is anelevation of a wire twisting :fea device in accordance with thisinvention.

Figure 2 is an enlarged fragmentary section taken at a point indicatedby the Vline 2*2 of Figurel. j

Figure 3 is a fragmentary section taken at Referringto the drawings indetail, the numerals 1 and 2 indicate a pair of handle members, thehandle member 1 having end portion 3 outwardly offset with respect to Ythe handle member 2 in order that the outer end portions of the handlemembers may be positioned a substantial distance apart with the innerend portions thereof positionedl comparatively close together and inparallel a point indicated by the line 3-8 of Figure'2.

wall of the opening 7. The handle member 2 is provided at its inner endwith a head 9` which is similar in every respect to the hea-,d 6.

The heads 6 and 9 are rotatably 4mounted upon a pair of annularshoulders l0 `formed exteriorly of a mutilated ratchetv 11.V Theshoulders 10 extend through the concentrically disposed openings in theheads 6v and9 and the heads are maintained in position on the shouldersby means of a pair of side plates 12 which are fixedly'secured to theratchet to form part-s thereof by suitablev bolts 13 extendingthroughthe' plates 12 and vinto the shoulders 10 and ratchet 11. The.ratchetlland plates 12v are formed in their, peripheral faces with arecess 14 which eX- tends inwardly beyond the axis'of the ratchet andplates. The recess 14' is' adaptedto be aligned with the' recesses 8 andwhen so aligned, the side walls of the recess 14 are flush with the sidewalls of therecesses 8. Having one end securedto the .plate `12 whichretains the head 9 is a pin 15 which projectsinto the recess 14 midway`'between the side walls of thelatten'- On opposite sides of the recess8, Vthe'head 6 is provided on its inner face with a pair of pawls-.lcand17 `for engagementwith the' teeth 18 on the peripheral face of theratchet l1. Each of the pawls is preferably formed of relativelystil,.resilient material, and is rigidly secured-to the head 6 inamann'ertohave its inner' end forced against theperipheryy of theratchet 11. The head 9 is provided on itsl inner face witha pair ofpawls Y19 and 2O similar to the pawls 16 and 17.

'ol-*Fica 1n the operation ofv thefdevice, Vthe.- ratchet y 11 isrotated lin a' manner to positiontherecess 14 in alignmentwith=thejrecesses ,8 in order Vthat-.a pair of'wires, such as 21maybere-v ceived through the recesses with the pin 1 5 extending-between thewires. One ofgtheI handle vmembers is then lreciprocatedjwhile theotherhandle member-is heldl stationary in order that the pinl may be rotatedwith rcspect to the wires to twist the latter. For eX- n' ample,the-handle member 2 is-held stationary y while vthe, handle member 1 isreciprocated v which causesthe pawls 16and 17 to rotate the l ratchet 11in a'cloclr-wisedirection asviewed in Figure 2. During the movement ofthe Y handle member 1 in a direction to cause the ratchet 11 toberotated by the pawls 16 and 17, the ratchet is rotated relative to thehead D 9 on the handle member. During movement Owing to the constantengagement of at least one of the pawls on the stationary handle memberwith the teeth 1S, there can be no return movement off the ratchet 11when the reciprocating handle member is moved relative thereto.

It is thought that the many advanta Oes of Y a wire twisting device inaccordance with this invention will be readily apparent, and althoughthe preferred embodiment oi the invention is as illustrated anddescribed, it is to be understood that changes in the site, shape andarrangement-of' parts may be resorted to, so long as such changes fallwithin the scope of the invention as deiined in the appended claims.

What I claim is y 1. A wire twisting device comprising, a rotatableratchet formed in its periphery with a recess extending inwardly bevondthe axis of the ratchet, a pin secured to the ratchet and extending intothe recess midway between the side walls of the latter,a pairof handlemembers rotatably mounted on the ratchet, and a pair of pawls carried.by each handle Y member for engagement with the-'ratchet on oppositesides of -said recess. Y

Q. A wire twisting device comprising, a roi tatable ratchet formedvinits 'periphery with a recess extending inwardly Abeyond the axis ofthe ratchet, a pin secured to the ratchet and extending into the recessmidway between the sidewalls of the latter; a pair of oppositelydisposed, annular shoulders formed on said ratchet, a Vpair of handle-members having their inner ends formed with substantiallydisk-shapedheads rotatably mounted on said shoulders,*each`-of saidheads being formed its ,periphery with arecess'corresponding in' widthto the'recess in the ratchet, and a pair-'pf pawls carried byeachheadffor 'engage-k ment with the ratchet on opposite sides of the recesstherein.`

VA wireitwisting device comprising, a roi m tat-able, ratchet formedv.with pair of oppositely disposed, annular shoulders, a'pair of handlemembers having vtheir inner ends formed with substantially disk-shapedheads A ,rotatably mounted lonsaid shoulders, each of. j m said headsbeing formed in its periphery with trolled solely through the pawls 17and 2O.V

a recess, a pair of plates fixedl-y secured to said shoulders formaintaining the heads in position thereon, said ratchet and plates beingformed in their peripheries with a recess adapted to be aligned withtherecesses in said heads and extending beyond the axis of the ratchet andplates, a pin secured to one of said plates and extending into therecess therein midway between the side walls of such recess, a pair ofpawls carried by each head for engagement with the ratchet on oppositesides of the recess therein, and a remov- A able extension for each ofsaid handle members. y
